Remarks

The GetValue method is a helper method used to determine the value of a field. If the BoundField object is being displayed in a designer and the field value cannot be determined at design time, the value returned from the GetDesignTimeValue method is returned instead of the actual field value.

Note

This method is used primarily by control developers.

Notes to Inheritors

When extending the BoundField class, you can override this method to provide a custom routine to determine a field's value.
